In this paper, we examine three interrelated issues: designing for teaching instructional design, the feasibility of constructivist ID methods and the multifaceted evaluation of computer-supported learning environments. After a brief review of the available literature, we present our own course which mixes traditional ID methods with the Crossley and Green’s practical guide for developing compu...

The talk1 describes an analytic approach to urn models of the Pólya type where an urn may contain balls of either of two colours. At each step, a ball is randomly drawn and replaced by balls of the two colours; a fixed 2× 2-matrix with constant row sum determines the replacement policy. The treatment starts from a partial differential equation associated with the model and bases itself on confo...

In Response: Regarding the comments by Berry et al. (1) on our previously published letter, we acknowledge that, in strict parasitological terms, confirmation of the diagnosis of urogenital schistosomiasis requires the identification of eggs by microscopic examination of urine. Nevertheless, we aimed at an operational case definition, providing criteria for identifying cases most likely to be t...

Quarkonia are meson states whose constituents are a charm or bottom quark and its correspondingantiquark (QQ̄). The study of the production of such bound states in high-energy hadron collisions represents an important test for the Quantum Chromo-Dynamics. Despite the fact that the quarkonium saga has already a 40-year history, the quarkonium production mechanism is still an open issue. There...

Philippe Ariès (1914–84) first won fame for his provocative rethinking of the history of childhood and the family [1], though his contributions have subsequently been severely criticized [2]. What then of his studies of the history of death? These too opened up an exciting new field of inquiry [3]. Have they stood the test of time, or suffered a similar fate? Indeed, has the whole history of de...

The Game of Life cellular automaton is a classical example of a massively parallel collision-based computing device. The automaton exhibits mobile patterns, gliders, and generators of the mobile patterns, glider guns, in its evolution. We show how to construct basic logical operations, AND, OR, NOT in space-time configurations of the cellular automaton. Also decomposition of complicated Boolean...
